The Goodman 20214203 is a genuine OEM condensate drain angle fitting engineered for the GCV90704CXBA 92%+ AFUE gas furnace and compatible GCV90-series models. This angled elbow redirects condensate flow around tight bends in the drainage circuit, connecting hoses and the trap while maintaining a smooth, leak-free path. A brittle or cracked angle fitting can leak acidic water onto the furnace base and control board, so timely replacement protects the entire unit.
The OEM 20214203 matches Goodman's exact barb size and bend angle for a snug, sealed fit. Generic elbows frequently have mismatched diameters that leak or pop off under condensate weight. The genuine fitting ensures reliable, drip-free drainage.
Very Easy (1/5). About 10 minutes. Cut power to the furnace, disconnect the hoses from the old angle, remove it, and press the new fitting into place with hoses reattached. Check for leaks after restoring condensate flow. No tools required.
